Variable Camshaft Timing Oil Control Solenoid

The variable camshaft timing oil control solenoid (also called the Camshaft Position (CMP) actuator) is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The variable camshaft timing oil control solenoid is controlled by the control module. The control module sends a pulse width modulated 12 volt signal to a variable camshaft timing oil control solenoid. The solenoid controls the amount of engine oil flow. The variable camshaft timing oil control solenoid can change the camshaft angle. The control module increases the pulse width to accomplish the desired camshaft operation.

Removal & Installation

2.4L Engine

Before servicing the vehicle, refer to the Precautions Section.

Remove the air cleaner outlet duct.

Disconnect the engine wiring harness electrical connectors (2, 3) from the appropriate Camshaft Position (CMP) actuator solenoid valve, also known as the Variable Camshaft Timing Oil Control Solenoid.
